What was felt?

Magnitude describes the event’s size. Shaking intensity describes effects at a location and can differ from place to place. These event-level values do not describe the shaking at your address.

Ground materials illustrated. These are not measured conditions at this event.

Soft soil and firm rock can respond differently to passing waves. Local shaking also depends on distance, depth and other conditions; a report’s magnitude alone cannot describe what someone felt.
